Emergency Management Queensland (EMQ) says residents in the state's south-east residents should prepare for more storms forecast to hit later today.
The weather bureau says isolated gusty thunderstorms are expected to hit the region by this evening.
The State Emergency Service received more than 150 calls for help after four storm cells swept through the region last night, bringing down trees and powerlines.
EMQ spokesman Mike Shapland says the SES is ready for any problems that arise today.
"It's really important, though, that people prepare themselves for these sort of events," he said.
"Have they got a plan, have they got an emergency kit, is their home secure, branches trimmed, gutters emptied?
"And are they listening to warnings?"
